Help save Gunner

Hello everyone this Gunner he is 1 1/2 years old German shepherd my bestfriend Trevor and his girlfriend Jill saved when he was still a puppy. They found him out in the cold, it was raining outside and he was very hungry. They tried everything to find him a home but nobody wanted a stray. They decided to take him in even tho they had two other dogs and only one of them work. Just recently they lost a baby of there own and has been spending a lot of money on hospital bills. April 25th Gunner got hit by a car and was stuck underneath the car where Trevor and Jill couldn’t do anything but pull him from the car and rush him to an emergency hospital! On the way they ran out of gas and had to flag someone down for help. Someone kindly pulled over and took them to the hospital where there was a 1500$ emergency deposit they had to put down just for them to see there dying dog! They then gave them the news that the dog was in shock and they wouldn’t know everything that was wrong with the dog until 24hours but Gunners lung was collapsing and his leg was definitely broken. They said there was a couple different payment options to keep him 24 hours and with only one of them working they went with the cheapest option, only a large amount of 5000$. They contacted every family member for help . The Dr then told them that after the 24 hours was done that Gunner would need a lunge surgery, that they still haven’t paid for. Right now they have a semi permanent breathing tub in his throat because he is unable to breathe on his own. We will keep you updated on everything as we know it . ANYTHING WILL HELP! 5-10-20$ anything will help. Please help save Gunners life ! He’s there world !
